Clutch plates

[Bob Culver]

What prompted the question? Do you mean the bare disc or the assembly? Despite customary lotsa slipping through the ages and loss of temper and of any set seem to work OK by Seven standard. The plain or later types with linings? The usual problem is the spline part worn and/or loose rivets. I gather some have managed to sort with carbide drills and re rivet. Whether done hot or cold I dunno.
